Specification of Letters Patent.

Patented Aug. 26, 1919.

Application filed December 1, 1917. Serial No. 204,948.

T 0 all whom it may concern Be it known that I, ALBERT H. SAw'rnnL, a citizen of the United States, residing at Providence, in the county of Providence and Stateof Rhode Island, have invented certain new and useful Improvements in Thread-Controller Devices, of which the following is a specification.

My invention relates to controllers for yarn, thread, silk, or other filaments adapted to be used upon creels or other textile frames for supportin the cops, bobbins or packages from which t e filaments are delivered.

The essential objects of my invention are to avoid dragging and fraying of the yarn or filaments as they are delivered from the controller; to insure a substantially'uniform tension of all the strands as they pass from the controller; to make the latter self adjustable to whatever position 'it may be induced by the direction of the threads pass ing therethrough; to make it unnecessary to employ a creel of V shaped or other inclined transverse section or of any particular dimension; to enable successful operation of the controller upon fine filaments such as silk without breaking such filaments; to lessen the number of parts of the controller, to adapt the latter to use with varying numbers of strands or filaments and to attain these ends in an inexpensive structure.

Further objects of my invention will appear from an examinatlon of the drawings and the following description.

To the above ends essentially my invention consists in such parts and combinations of parts as fall Within the scope of the appended claims.

In the accompanying drawings which are a part of this specification, and in which is shown merely a preferred form of embodiment of my invention,

Figure 1 is an end elevation of a creel or frame upon which my controllers are mounted, I

Fig.2, a plan View of the same,

Figs. 3, 4, 5 and 6, rear, front, and end elevations, and a plan, respectively of a controller, and

Fig. 7, a section of the same on line 7-7 of Fig. 3.

Like reference characters indicate like parts throughout the views.

-The invention will be described in connection with the specific embodiment shown,

, and it will be understood that the invention is not to be limited by such specific showing except for such limitations as the claims impart.

The creel or other similar textile frame is shown in this construction as embodying uprights 10 supported by standards 11, and carrying forwardly directed brackets 12 and rearwardly directed brackets 13, in which are respectively mounted the controller supporting bars 15 and the bobbin, cop, or spool holder supporting bars 16. Upon the latter are the holder bases 18 Whose spindles 19 carry bobbins 20. The tops of the spindles are in the rear of, and preferably in substantially the horizontal plane of, the rods 15 upon which the controllers 22 are mounted. The threads, strands, or yarn 23 from the bobbins pass through the controllers to winding means whichmay be, for instance, a beam, or bobbin mounted on an extended frame. When the winding means consists of a beam shorter than the creel the threads 23 are inclined to laterally converge as they leave the creel, in the manner shown in Fi 2. If the frame carrying the winding bo ins is of greater length than the creel, the threads are divergent from, the creel.

In detail each controller comprises an attaching means consisting of a circular base portion 25 integral with which are downwardly dri-reo ted inclined side walls 26 provided in their lower mar 'ns with oppositely disposed open slots 2 to receive its supporting rod 15. Integral with the rear of the walls is a cross piece 28 provided with a threaded opening 30 to receive a screw 32 for clamping the base to the supporting rod.

Upon the described attaching means or bracket is pivotally mounted or movable on vertical swivels the substantially rectangular cont-roller body or frame comprising, in this instance, an oblong base 34 resting on the bracket portion 25 and provided with a central threaded perforation 35 adapted to receive the threaded shank 36 of a screw 37 having an enlarged shoulder 38 loose in an opening 39 in the portion 25, and having a head 40 abutting against the lower face of the latter. Integral with each end of the basev is a vertical end wall 42 provided with a central vertical guide slot or bearing 44 extendi from the top to the base. Forwardly. of t e slot is a vertical groove 46 open at the top and terminating above .the

base 34 adapted to slidably receive one end of an oblon guide plate 47, preferably of glass, provi ed with a row of holes 48. Each wall has also an inclined groove 49 at the rear side of the guide slot extending to the base 34 to slidably admit one end of a glass guide plate 50 provided with a horizontal series of holes 51 corresponding in number to the holes 48. V I Resting on the floor of the body is an oblong block or abutment 53 of glass or other refractory material with its ends extending into the guide slots. It is rectangular in' cross section except that its top or operatingface is curved as at 54. The rectangular formation prevents rotation of, the abutment, but it is sufficiently loose in the slotsto permit its facile insertion or removal therefrom. A metallic roller 56, preferably tubular, rests upon the abutment with its ends also loose in the guide slots 44. The latter serve as bearings for the roller and maintain it in vertical alinement with the abutment, yet its ends are loose to permit it to be removed with ease or 'to accommodate threads of varying sizes.

The threads pass from the bobbins on the spindles '19 first through the holes 51, then between the abutment and roller, and thencev through the holes 48 to the winding means or device. In their passage between the abutment and roller the threads are straightened and smoothed, and a too free delivery of the threads from the bobbin prevented.

The removable character of the guide plates permits substitution of those having dif, ferent numbers of holes when different numbers of threads are to be employed. The use of glass as the material for various arts furnishes smooth and nonwearing suraces for contact with the threads, and makes it unnecessary to insert porcelain eyelets in the holes. In treating fine threads such as silk it is essential, in order to prevent breakage, that the roller 56 be supported as shown exclusively by the threads themselves. The stationary character of the abutment relatively to the rotary character of the roller insures the desired degree of smooting action of the parts upon the filaments.

It will be noted that in each cluster of four threads passing through a, controller,

the outside threads would be subjected to great friction in passing through the guide plates if the latter were stationary, and would tend to abrade or break fine threads. The pivotal character of the controllers modifies this tendency, and furthermore enablesa straight creel or frame to be employed where otherwise a V or other special shaped creel would be required.

I claim 1. The combination in a textile frame, of

bars in the frame, supports on the bars, controller bodies comprising bases resting on the supports and end walls, swivels in the supports engaging the bases, and rollers in the bodies engaging the walls.

2. In a device of the character described, the combination of a support, a horizontally rotatable body pivotally mounted on the support to serve as a controller, an abutment in the body, and a roller resting on the abutment.

3. In a device of the character described, the combination of a support, a horizontally rotatable body mounted on the support to serve as a controller, a'stationary abutment in the body provided with a convex operating face, a roller resting upon the abutment and supported solely by the abutment, and upright guide plates upon thebody disposed at opposite sides of the abutment and roller provided with series of guide holes.

4. In a device of the character described, the combination of a support, a horizontally rotatable body comprising a base mounted on the support to serve as a controller, up?

wardly directed grooves at each side of theslots, an abutment in the slots, a roller loose in slots resting on the abutment, and guide plates slidably mounted in the grooves provided with guide holes.

6. In a device of the character described,

the combination with a textile frame, of bars therein, bobbin holders on said bars, spindles on the holders, bars in the frame above the holders, supports on the second bars and horizontally rotatable controllers pivotally mounted on the supports and adapted to cooperate with said holders.

In testimony whereof I have-aflixed my signature.

ALBERT H. SAWTELL.
